What are the different types of Audi A3 models?

I am interested in purchasing an Audi A3 but I am confused by the different models available. Can someone break down the differences for me?

There are currently three different models of the Audi A3 available: the A3 Sedan, A3 Cabriolet, and A3 Sportback e-tron. Each model has its own unique features and options, so it's important to determine which one best fits your needs and preferences before making a decision.
